Title: Variable buoyancy linterline float using multifunctional auxiliary pipe
Inventor: SHIMAMOTO HITOSHI
IPC: A01K93/00
Filed: 2001-09-25
Abstract: PROBLEM TO BE SOLVED: To solve the problems that the passage of a fishing line is bad due to a line habit with slow adaptation of terminal tackles when the lower depth of the float is increased with the light terminal tackles because the float has a through-hole for passing the fishing line therethrough in floating terminal tackles of an interline float and further the stability of the interline float is worse than that of the fixed terminal tackles of the interline float because a float fixing body is located at the tip of the float and that it is necessary to prepare a plurality of floats having different buoyancy, cut the fishing line and exchange the floats for changing the buoyancy and much time and labor are further required for exchange with more parts accompanying the terminal tackles because the buoyancy of the interline float is fixed. SOLUTION: This interline float is obtained by enlarging the inside diameter of the through-hole of the interline float from that of a conventional float, inserting and mounting an auxiliary pipe from the through-hole at the bottom. Thereby, a sinker or an auxiliary body for regulating the buoyancy can be added to the auxiliary pipe without cutting the fishing line.

IPC: G21K5/00
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam device eliminating the influence on image signals of secondary electrons and/or reflected electrons from DC component of visible light.
